Replace fetch-deals, fetch-promos, fetch-chargebacks with a single
/api/fetch-mkt-data?file=deals|promos|chargebacks endpoint.
Update MktDataView fetch calls accordingly.

Replace all mock data in the Profitability Dashboard with live data:
- Add 3 new API routes (fetch-deals, fetch-promos, fetch-chargebacks) proxying Dropbox Excel files
- MktDataView now accepts rawData/adsData props and fetches+parses the 3 new files on mount
- SELL OUT and units aggregated globally across all marketplaces from rawData
- PPC Spend aggregated globally from adsData; ACoS calculated as spend/sales
- Deals (col A→C), Promos (col E→K), Chargebacks (col AN→B) parsed and summed per ASIN
- Category filter populated from product line metadata
- Loading skeleton shown while files are fetching
